Priority - Priority is the chance of success for a move. Basically if the move has good range and speed, it has good priority. Moves that have high priority and do solid damage are among the best moves in any fighting game. These moves should be the foundation for your character most of the time, and should be the moves you rely on when you have nothing else to really work with.

Pokes - Pokes are moves that are fast,have high priority and are safe MOST of the time. They don't neccessarily have great range, but they are very reliable and can be used in a multitude of ways(to defend, to initiate offense,etc). Pokes come in high,mid and low variations(if you don't understand what I mean, go down to number 4).

Safe - Safe moves are ones that are relatively unpunishable if the opponent blocks it(meaning you can quickly more away or block afterwards). It's really as simple as that. Characters who have save options that leads to rewarding results on hit are normally the best characters.

High,Mid,Low - These are the 3 main ways a move can hit. [H] = High (overhead) moves which must be stand blocked, but cannot be crouch blocked. [M] =Mid moves which can be blocked either way. [L] = Low moves which can be only crouch blocked but cannot be stand blocked (they also cannot be evaded by Lay Down maneuvers). [dM]/[dH] = duckable Mid (duckable High) moves which can be stand blocked, but also can be simply evaded by crouching (that is, unless your character's size is huge). [A] = Anti-aerial moves which are more upwards-aimed and can hit only airborne opponent. [U] = Unblockable move that cannot be blocked either way;

Throw/Grab - A grapple/grab that is unblockable, and most of the time cannot be ducked, it works at close range only since body contact with victim is needed. Throws are used to stop heavy blockers and to break down defenses. [G] = Grab move, mostly seen in 2D games; [dG] = duckable Grab move, mostly seen in 3D games.

Properties - Basically how the move works. Where does it hit? About how many frames is it? Does it track sidesteppers? Does it go under low attacks? etc,etc.

Stuff - Stuffing a move is basically using a move that has priority over the move being used against you to beat it out. Example is Basara's Guard Destroyer grab in SS5sp, with priority that overrides most of game's moveset

Top Tier - A character that is considered to be one of the best in the game. Top tier characters are SIGNIFICANTLY better than the others, and have overpowering moves that are normally safe and highly rewarding. In most fighting games, there is one character who's so good that he almost transcends into his/her own tier. This is known as "Broken Tier", or "God Tier".

Mid Tier - This is the trickiest to analyze, because it's seperated into 3 mini divisions basically: upper mid, mid and lower mid. Mid tier characters have the tools to compete and are noticeably better than the low tier characters, but not as dominant as top tier characters. Upper mid tier characters are noticeably better than the other mid tiers, mid tiers are right down the middle(average characters) and lower mid tiers are decent, but are more often mistaked for/considered to be low tier.

Low Tier - Characters who are lacking the tools needed to consistantly win/compete at the highest level. Talented players can take these characters to new heights, but eventually their limit will be reached, and they will lose.

Clan - a group, or "cliq" of players who represent one another when they fight. Clans are more relevant in games where team play is involved(FPS,MMORPG), but are frequently seen in fighting game communities as well(tekken,mk,sc,sf). It's not uncommon to see clan battles to determine who's the most dominant clan.

Scrub - "A derogative term, mostly synonymous with "loser." It is usually used to indicate a player whose skill level is low or who is deemed to simply be unable to win, but most importantly it indicates the player who has a mindset that prevents him from gaining skill and experience, as he sees the problem in anything except himself. Scrubs are usually either beginners to their chosen game, players who simply lack the raw skill to succeed (though they may have a high understanding of advanced play), and players who are not willing to advance their tactics. Members of the last group are commonly not willing to learn, not able to adapt to high-level play, and often complain about losing to "cheap" tactics. Other types of scrubs includes people who are more interested in the aesthetics of how to play a beautiful game rather than how to play a winning game. e.g. They may be lose because they are preoccupied with ending the match with a certain special move. Hence their opinion that someone who wins regardless of the tactics may be "cheap.""

GG - good game. said out of respect for the opponent for putting up solid fights. common to see this in a chess match, a pick up game of basketball and obviously in fighting game communities.

Frames - the speed of a move. The lower the number of frames, the faster it is.

Yomi/Mind Games - "Mind games are described as the use of psychology to maximize one's chances of winning. A big part of mind games is archetyping, dissecting the way an opponent plays and then immediately gearing oneself to prepare an effective counter strategy, as well as a great deal of other tactics that take advantage of the amount of predictability present within an opponent."

Pitbull - A person who's very offense-oriented. Some characters are most effective when played in a pitbull manner

Turtle - A person who's very defense-oriented. Some characters are most effective when played in a turtle manner. Turtling often has the point to win by time out while being ahead on health. Scrubs look down on turtlers as being "cheap", having no skill or being a pussy. Yeah, because we all should use fighting games as a measuring stick for one's manliness.

High-Low game, Mixups, 50/50 - Mixing up attacks that require opponent to defend differently to stop the opponent from consistantly blocking the same way. This is essential in almost any video game. High-Low game consists of mixing high-hitting attacks with low-hitting ones, usually at close range. Mixups can be expanded beyond this however, as Grabs and quick attacks can be implemented by attacker, and various evades can be implemented by opponent. 50/50 term refers to equally rewarding mixup, for example where high and low attacks have same speed, range, recovery. This way there is equal risk/reward for using both of them, which breaks the game and turns it into pure guessing as Rock-Paper-Scissors.

Punish - Hitting the opponent for doing a move that is unsafe. Punishing is one of the key aspects of any fighting game. You must punish a move if you see it's unsafe.

Punisher - Basically a move that you only use to punish something. It is normally not wise to throw these moves out of nowhere, because they are unsafe most of the time.

Tick Throw - A technique where attacker conditions the opponent into constant blocking by spamming fast and safe attacks on him, then when he ensures opponent is stuck in block, attacker grabs and throws him. Since opponent doesnt knows after how many "ticks" grab will take place, he cannot release block in needed moment to retaliate to grab.

Main - Fighting game slang for your best character. If someone wants to know who's your "main character" they want to know who your best character is.

It kinda made those phrases popular among the FG community for a while. Then in an interview with Justin I found recently, he explains what they mean and tells he had a hand in creating them. (My post was more or less a joke anyway).
